This is an update on my 2500 diesel problem for those interested. Since I have the extended warranty, the Dealer ordered the recommend replacement for the uplift pump, one which got installed in the fuel tank. The next day, I drove the truck to work. The loss of power problem continues. I had to down shift from 6 to 5th gear on some of the hills when the engine began to lug. This is while moving at 50+ mph. The truck is going back to the dealer for more trouble shooting. The truck which I bought new has about
66,000 miles and all service have been performed by the dealer. The fuel filter was replaced during a previous service. Yes, I'm getting desperate.John
